Elastic: Lessc v4 comptibility issue: media definitions require block statements

[tfl]

I have trouble lessc'ing Elastic style with lessc 4:

lessc -l -m=always styles/styles.less gives me

SyntaxError: media definitions require block statements after any features in styles/widgets/editor.less on line 632, column 5:
631
632     .mce-menu {
633         width: @layout-mobile-menu-width !important;

• Archlinux
• Roundcube version 1.4.10 (github checkout)
• Node: v15.5.1
• lessc 4.0.0 (Less Compiler) [JavaScript]

One more reason for #6284. This way not everybody needs to worry about the right tooling for building the css files.

I was going to say wontfix for 1.4, but there's a PR so maybe it wont be much trouble to fix. Does the PR fix the issue above? I didn't encounter such an issue using less v4.

The 1.4 branch also probably should get 7df5e5f.

Does the PR fix the issue above?

Yet, it does.

[tfl]

Well, no. It does not - at least for me. Yes, it may fix those errors based upon mathematical calculations (which I fixed by myself previously) but it does not reference (nor fix) the error I mentioned above.

For the time beeing I downgraded lessc to 2.7.3 and now I have my styles back. I do not know since when RC less-styles became incompatible with current lessc but RC v1.4.9 styles are incompatible too.

@tfl Do we use the same compiler?

npm install less
npm install less-plugin-clean-css

I tried it again with changes in PR and that syntax error has gone.

[tfl]

You are right! I cloned https://github.com/vookimedlo/roundcubemail.git and lessc now has nothing to complain.
BTW: we use(d) the same compiler (see my initial post)

[alecpl]

Fixed.
